Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for thickness and signs of uneven wear.
3
Examine wheel lug nut torque to ensure they are properly tightened.
4
Inspect suspension components for wear or damage (e.g., tie rods, control arms).
5
Verify wheel alignment using a professional alignment tool.

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery if working near electrical components.

2. Remove Wheel

Use a socket set to loosen the lug nuts slightly while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Check for warping using a dial indicator; if warped beyond specifications, replace.
- If the rotors are within spec but have uneven wear, consider resurfacing or replacing.
Replace Brake Pads:
- Remove the caliper bolts using a socket.
- Slide the caliper off the rotor and remove the old brake pads.
- Install new brake pads, ensuring they are properly aligned.
- Reinstall the caliper and tighten the caliper bolts to the manufacturer's torque specifications (typically 20-25 ft-lbs).

4. Reinstall Wheel and Lower Vehicle

Place the wheel back onto the hub.
Hand-tighten the lug nuts before lowering the vehicle.
Once on the ground, torque the lug nuts to the manufacturer's specifications (usually 76-80 ft-lbs).

5. Final Checks

Inspect for any brake fluid leaks.
Ensure all components are secured and no tools are left behind.
Reconnect the battery if it was disconnected.
